Project description:We used single cell RNA-seq to comprehensively map raphidophyte Heterosigma akashiwo to grow under present and future ocean conditions. We unveiled several unique types of metabolic changes, signaling pathways, and regulons associated with these cells.
Project description:Human tracheobronchial epithelial (HTBE) cells are considered to serve as a good correlate of influenza virus infection in the human respiratory tract. mRNA-Seq analysis was used to profile the cellular transcriptome of HTBE cells at multiple time points in response to infection with influenza A/California/04/09 (H1N1), A/Wyoming/03/03 (H3N2), and A/Vietnam/1203/04 (H5N1) HALo virus. The Influenza A/Vietnam/1203/04 (H5N1) HALo mutant virus is an attenuated H5N1 virus generated from wild-type Influenza A/Vietnam/1203/04 (H5N1) virus as described in Steel, J., et al. J Virol. 2009 Feb; 83(4):1742-53.
Project description:<p>Four species of phytoplankton representing important bloom-forming species from three globally important phyla (Bacillariophyta, Haptophyta, and Ochrophyte) were cultured in this study. These species include the cosmopolitan diatom <em>Chaetoceros affinis</em> CCMP159 (isolated from Great South Bay, NY, USA, 1958), the haptophytes<em> Chrysochromulina polylepis </em>CCMP1757 (isolated from the North Sea 1988) and <em>Gephyrocapsa oceanica</em> RCC1303 (isolated from Arachon Bay, France, Jan 1999), and the raphidophyte <em>Heterosigma akashiwo </em>strain CCMP 2393 (isolated from Rehoboth Bay, Delaware, USA). Cultures were grown under three conditions: nitrogen-stress, phosphorus-stress, and replete conditions. Intracellular metabolites were extracted from cultures and analyzed with targeted and untargeted mass spectrometry-based metabolomics methods.</p>
Project description:The purpose is to obtain samples for virus titration, transcriptome, bioplex and histopathology analysis of mouse lungs after etoposide treatment and infection with a pandemic H1N1 influenza strain.
